Embodiment 1

[0016] 1. Collect Eucommia male flowers. During the blooming period of Eucommia male flowers in spring from March to April, fresh Eucommia male flowers are manually collected to remove impurities, and the carefully selected Eucommia male flowers are spread out in a ventilated and dry place for 5-16 hours.

[0017] 2. Knead into a needle shape.

[0018] 3. The formed eucommia male flowers are quickly transferred into a 2mm stainless steel wire mesh frame with a thickness of 2-3cm, and the stainless steel wire mesh frame containing the eucommia male flowers is transferred to a -50°C refrigerator for freezing for 6 hours.

[0019] 4. Take it out after freezing, and quickly transfer to a vacuum freeze dryer at -50°C for vacuum freeze drying. If the action is slow, the eucommia male flowers will thaw, and continue to freeze in the drying chamber of the freeze dryer at -50°C for 0.5-1 hour. Then turn on the vacuum pump to directly sublimate and vaporize the ice crystals in the mal...

Embodiment 2

[0024] 1. Collect Eucommia male flowers. During the blooming period of Eucommia male flowers in spring from March to April, fresh Eucommia male flowers are manually collected to remove impurities, and the carefully selected Eucommia male flowers are spread out in a ventilated and dry place for 5-16 hours.

[0025] 2. Knead into a needle shape.

[0026] 3. The formed eucommia male flowers are quickly transferred into a 2mm stainless steel wire mesh frame with a thickness of 2-3cm, and the stainless steel wire mesh frame containing the eucommia male flowers is transferred to a -70°C refrigerator for quick freezing for 2 hours.

[0027] 4. Take out after quick-freezing, and quickly transfer to a -50°C vacuum freeze dryer for vacuum freeze-drying. Then turn on the vacuum pump, observe that the vacuum degree drops slowly, make sure that there is no air leakage, and the vacuum degree gradually drops to 0.5-10Pa, at this time, the ice crystals in the male flowers directly sublimate ...

Embodiment 3

[0032] 1. Collect Eucommia male flowers. During the blooming period of Eucommia male flowers from March to April in spring, fresh Eucommia male flowers are collected manually to remove impurities, and the carefully selected Eucommia male flowers are spread out in a ventilated and dry place for 10 hours.

[0033] 2. Knead into a needle shape.

[0034] 3. The formed eucommia male flowers are quickly transferred to a 2mm stainless steel wire mesh frame with a thickness of 2-3cm, and the stainless steel wire mesh frame containing the eucommia male flowers is transferred to a -35°C refrigerator for 5 hours of freezing.

[0035] 4. Take it out after freezing, and quickly transfer to the nearest -35°C vacuum freeze dryer for vacuum freeze dryer. Then turn on the vacuum pump and observe the data of the vacuum degree to drop slowly to ensure that there is no air leakage. The vacuum degree gradually drops to 0.5-10Pa.

[0036] 5. Vacuum freeze-dry for 17 hours, and measure the moistur...

Abstract

The invention discloses a method for producing eucommia male flower tea, which comprises the steps of selecting eucommia male flowers, twisting for forming, quickly freezing, freezing and drying under vacuum, killing green and promoting fragrance, and cooling and sieving. In the invention, an ultralow-temperature quick freezing and low-temperature and vacuum freezing are adopted to dry the eucommia male flowers, so the active ingredients in the eucommia male flowers are hardly damaged; and the effect of the method is better than common tea preparation method. The eucommia male flower tea product prepared by the method is needle-like and green, and the shape of the eucommia male flower tea is almost the same as that before freezing. The tea water made by the tea prepared by the invention is green and orange, has a mellow flavor, and tastes sweet and agreeable and the aftertaste of the tea lasts long.
